Yeah there is a lack of cloud storage of your local files. Kind of defeats having the option of playing local files.
Though for me Spotify is pretty good. I just hope that some bands out there that just "don't get streaming services" and refuse their catalogue to appear. Excuses like their music should not be able to download as one track, the experience is the full album. Or don't get not owning the physical album. Looking at Spotify now, just shows if they don't want want people downloading their files. Then, get on board for people to be able to legally download their music.
